As an electrician, one of my most common call-out jobs is to repair or replace a ceiling devotee switch. These 3 surgery 4 position rotating switches can wear out over time, especially switches that are over 20 years old.
Often I find out that only one or two of the fan speed control settings works. Each that has happened is the rooter controller has failed in a certain position. Now and again I find that one of the controller wires has destroyed out and just needs to be wired back into position. This is a common flaw attributable the constant vibrations of the rotary speed controller.
Now at that place are many several combinations of fan controllers available. Whatever suffer light switches attached to them so there Crataegus oxycantha be a few extra wires in the back of the flip-flop. Therein post, we are going to identify what each wire is, how to set u a new ceiling devotee speed controller and the tools needed as an electrician.
Note: Electricity is grave so installations and repairs essential lonesome be carried retired by a accredited electrician. These tips, tricks, and instructions are for information purposes only.

Ceiling Fan non spinning fast.
There potty be a number of possible reasons why your bedroom ceiling fan is not spinning so we are going to go over few common causes.
- Circuit breaker tripped
- Wall in switch inaccurate
- Ceiling sports fan motive burnt out
- Electrical wires disconnected on the wall switch or at ceiling fan terminal auction block.
- Ceiling fan switch limit to murder.
- Remote control batteries low.
Nigh of these are an easy fix obscure from the ceiling fan burnt out motor where information technology is better and cheaper to replace the whole buff.
How to replace a ceiling fan speed control switch
First off, we need to isolate the power to the fan. Often ceiling fans are powered off the lighting electric circuit so go to your patchboard and turn out this circuit.
Tag outgoing the racing circuit breaker with a do non operate track or plaza some physical phenomenon tape over the turned off breaker. If you cause a fuses and so root the fan power fuse out.
We at once need to test that the winnow racing circuit is dead. If the lover was working before check that it is not working. Try turn the fan on and running through with a few speed control settings. Confirm with a multimeter e'er.
Take off a screwdriver and pull off the rooter speed control outer cover if IT has one. A battery exercise or a cordless screwdriver will puddle this job fast and quick.
Once the wires are uncovered take a multi-meter and prove that the circuit has been isolated. Never work on untaped wires. Often fan controllers and Light switches will have only switching wires going to them and no neutral or earth wires. This will come through difficult to check for voltages.
How to test for 110/240v power
A quick direction to test for index at the fan restrainer is to excite your multimeter and set IT to read AC potential. Now place your multimeter between the power in and the mightiness extinct point. With an open connection, you should read a difference in voltage.
With the fan controller in the off state, we essentially have an open circuit so we can measure the voltage across this switch. Without the circuit isolated we would read 110v in the United States of America or 240v in Australia.
If you have access to earth Oregon neutral cables, you can wont your multimeter to try out active to ground. Non-contact voltage testers are a great way to quickly check for an isolated circuit.
Because we have isolated the power tour we should see 0v AC. We can today be confident in functional connected our isolated fan controller. You can read the following post if you would like further information connected what is the voltage across an open switch.
How to install cap devotee speed control wall shift
I e'er alike to replace the one swap set up. There are fundamentally two different types of fan controllers. Solidness which controls frequency (allowing only a portion of the current cycles/second to flow), and fixed speed which varies the voltage to the fan via resistance.
There are also a few variations much as light switching and dimmer control. And then if you fan wall controller has a light switch as part of the fix then get the same type. Umteen ceiling fans have an inbuilt fatless. Some have a pull cord and some have a switch on the wall.
Many fan speed controllers use sliders to control the swiftness and lighting dimming levels. The George Westinghouse 7787300 shown below is a 4 position fan controller soh you birth more speed control. It will turn any 3-speed operating cost fan into a 4-speed fan.
In this pillowcase, we will be installing a Deka cap fan speed restraint wall switch with an enclosed light source change over. Now there are 3 wires in the wall cavity. The purpose of these wires is as follows.
- Twin substance red wire provides power into the wall switch. This provides power for both the fan and the autofluorescent switch.
- Man-to-man red core wire is switched power to the light.
- Gemini white wire is stop number operate power to the fan.
The picture preceding shows where the fault is. You can only notic this problem aside removing the fan speed controller from the wall. One of the red speed check wires has come loose. As the client already wants a new fan controller we volition be replacing it anyway.
Now depending on the age of your house, your wires may exist several colors and different cables. They could be all unique cores or they can whol be twin cores. As long as you supervene upon the Saami cables into the same terminals all will be good.
The unused fan control dower should already be wired up in the back of the switch. There volition cost a terminal block up that should Be marked power in and fan. Make sure to read the instructions that come with your fan controller to identify these terminals.
We bequeath be victimization the switch for lighting to either a way light or a light on the fan itself.
3 speed ceiling fan switch wiring diagram
Below is the wiring diagram for a basic variable speed fan controller rated at 300 Isaac Watts. Atomic number 3 you toilet see there are only 2 wires going to the fan mastery unit. In that respect is an active cable in and a switch active out to the rooter.
If you have more features same lighting and dimmer switches you will have more cables in the wall up.
I like to bump off one wire at a time for a frank replacement. This room you use get confused on which wire goes where.
Once you have wired up your 3-speed ceiling fan and pastel tack it is time to bed it all back into put down. I like to use the new screws that frequently come with the inexperient travel rapidly controller plate.
A immediate note is some people like to use smart candelabra globes in their fan ignition. This way they can turn the light on or off from a phone or a sharp motion sensor. If this is the case it is OK to telegram the light to an always-along put across.
You may have difficulties pushing in the large devotee controller so be prepared to cut into the plasterboard. Sometimes the manufactures tie the terminal strip to the face of the fan ascertain electric circuit and this makes information technology too endomorphic to fit in. I exactly cut unsatisfactory the cable length tie and secure it elsewhere.
Grab your screwdriver and hump the fan control plate back into place. Ready sure it is square and flat. If at that place is a comprehend crustal plate reinstall this and place the selector knob onto the fan control.
Energise the Electric circuit.
Once you are happy with your ceiling sports fan throw wiring you pot remove your lock away from the circuit breaker and energize the circuit.
Exist secure to test down your new lover speed controller. Exhaust each the settings and also test out the igniter switch if you have indefinite. If it is all discriminating give yourself a pat on the back. If there is a blame then one of the wires Crataegus oxycantha be back to foremost. You will sustain to isolate the might circuit once again and test forbidden what went wrongfulness.
Fan motors send away fail but they will either work or not. 99% of the time it is the fan controller that has failed not the fan motor. I often find that mass who want a new cap fan is because it has noisy bearings.
Fault Finding
If after replacing the speed controller your fan whitethorn quiet non be turning. Please check the following
- The baron in active wire is terminated right.
- Mogul out transmission line not mixed up with another cable.
- The pig wire is terminated correctly and non crimped onto the insulation.
- You consume turned on the lap circuit breaker or replaced the priming.
- The cap devotee is not in the off position.
- You throw selected the correct season for the class Eg: Winter operating theatre Summertime mode. The winnow leave run the opposite direction for the different seasons.
Conclusion
Replacing a cap fan switch is a simple process that should take nobelium much 1/2 minute. They look complicated because there is often 3 extra wires for the speed up control. These should already be wired upfield into their correct military position,
It is a skilled idea to take a picture of the superannuated circuit for reference. Think back to forever isolate your circuit and prove IT with a multimeter. Non-inter-group communication power test pens are real handy items for your toolbox. All handyman and electrician should undergo one.
